The ISO 4217 code for Canada’s official currency, the Canadian dollar, is CAD.
The Canadian dollar is issued by the Bank of Canada and is divided into 100 cents. Its symbol is commonly written as $, although CA$ or C$ can distinguish it from other dollar currencies. The currency has been Canada’s monetary unit since the 19th century, with the modern dollar emerging from monetary reforms after Canadian Confederation.
CAD is the three-letter code used by banks, currency exchanges, financial markets and international payment systems. The first two letters identify Canada under the ISO country-code system, while the final letter identifies the dollar. This format helps prevent confusion with USD, AUD and NZD, which represent other national dollar currencies.
The Canadian dollar is often informally called the “loonie,” a nickname derived from the loon depicted on the one-dollar coin. The two-dollar coin is known as the “toonie.”
